Implemented as Avisynth C-plugin (not regular Avisynth plugin).

-----------------------------------------------
Must be loaded with Load_Stdcall_plugin("yadif.dll") or LoadCplugin("yadif.dll") (not LoadPlugin !). Do not use autoloading. (Note: in Avisynth v2.5.7 there is no need for explicit loading of Avisynth_c.dll by user for such plugins.)
+
'''Back to [[External_filters#Deinterlacing|External Filters]] &larr;'''
 
+
Tested in Avisynth v2.5.7 (probably works with v2.5.6 and above).
+
 
+
Field parity of source clip must be properly set (use AssumeTFF, AssumeBFF).
+
 
+
Very fast. Assembler SSEMMX optimization from mplayer (compiled with MinGW GCC).
+
 
+
YUY2, Planar YV12 color format only.

Description

Port of YADIF (Yet Another DeInterlacing Filter) from MPlayer by Michael Niedermayer. It check pixels of previous, current and next frames to re-create the missed field by some local adaptive method (edge-directed interpolation) and uses spatial check to prevent most artifacts.


Requirements

- AviSynth 2.5.8 or later
- Supported color formats: YV12


Syntax and Parameters

Yadif (clip, int "mode", int "order", bool "planar", int "opt")


clip   =
Input clip


int  mode = 0
  • 0 : single frame rate, temporal and spatial interlacing check (default).
  • 1 : double frame rate, temporal and spatial interlacing check.
  • 2 : single frame rate, skips spatial interlacing check.
  • 3 : double frame rate, skips spatial interlacing check.


int  order = 1
  • -1 : field order as Avisynth assumes (default).
  • 0 : bottom field first
  • 1 : top field first


bool  planar = false
  • false : usual YV12 colorspace (default); if input clip is YV12 this parameter is silently ignored.
  • true : flag for (hacked) planar YUY2 color format of input and output clips, compatible with Interleaved2planar and Planar2Interleaved functions from the RemoveGrain (SSETools) plugin.


int  opt = 0
  • -1 : CPU optimization - auto (default).
  • 0 : slow C version.
  • 1 : Integer SSE
  • 2 : SSE2
  • 3 : SSSE3 (some)


Examples

Yadif with default settings:

AviSource("blah.avi")
Yadif(mode=0, order=-1, planar=false, opt=-1)
